237f6c708a Don't modify req->error for IOs outside io engines 
`req->error` should be modified by the request's owner only; hence, if
the request has been allocated to handle IO (i.e. it's not an internal OCF
request) only engines can change it

Use management queue for parallelized management operations

Rafal Stefanowski
97ee3af8f7 Use management queue for parallelized management operations 
When IO queues are used for parallelized management operations,
e.g. changing cleaning policy, a deadlock may occur due to global
metadata lock interfering with taking request from IO queue,
as they might be run on the same thread. As a workaround using
a management queue specifically for such operations eliminates
this problem.

39d566c280 Replace submit with forward in ocf_metadata_read_sb() 
This one is quite special, because it can be called before cache is
instantiated, which means we can not allocate the request using
ocf_req_new_mngt() due to absence of mngt_queue. For that reason we
simply allocate request using env_zalloc() and then release it with
env_free(). The lifecycle of the request is very straightforward and
the only used fields are forward counter and callback.

cache_forward* callback and counter, because they will not be used
in this context anyway.
